PORTABLE ENGINE FOR USE IN REMOVlNG BARK FROM STANDING TREES, dc.

SPECIFICATION forming part of Letters Patent No. 739,785, dated September 22,

Original application filed October 4, 1902, Serial No. 125,998. Divided and this application filed October 4, 1902. Serial No. 125,999. (No model.)

To all whom, it may concern:

Be it known that I, WELLINGTON PARKER KIDDER, a citizen of the United States, residing zit-Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Portments used in removing bark from standing trees and also provide such implements with compressed air for their actuation.

My new engine is illustrated, but not claimed, in my application, Serial No. 125,998 of even date, for apparatus for removing bark from standing trees. I

In the drawing, 1 is the engine-base, of any suitable construction, preferably provided with lateral wings 2, there being one wing at each corner of the base 1. These wings are preferably bored at 3, so that stakes or pins may be driven therethrough into the ground to hold the base and its supported parts in place temporarily. The base is also provided with an opening 4 in an anchoring device in the form of a bight 7 on that side from which the winding-drum 5 projects to receive the wound-on chain 6. Through the bight 7 a stake 5 may be driven to help anchor the engine temporarily in place, and especially to resist the pull on the chain 6 taken up on the winding-drum. The foregoing statement is made for the sake of clearness, but is only incidentally relevant to the main novelty of my present invention.

Base 1 supports a motor 9 of any suitable kind or construction, and therefore I do not herein specifically-describe the motor further than to state that its driving-shaft 10 is provided with a small gear 11. Next to the motor I secure on the base an air-compressor 12 and air-receiver 13, which is connected with the air-compressor by the usual conduit 14.-.

The air-compressor and air-receiver may be of any desired construction, and hence I do not specifically describe the present compressor and air-receiver, which, like the motor, are of varying constructions and kinds and known in detail to all persons skilled in the arts to which they relate.

In carrying out my invention I lengthen the usual transverse shaft 15 of the air-compressor (and which has heretofore been used, so far as I am advised, solely for the purpose of actuating the piston-rod and piston) and make it long enough to project from the side of the aiccompressor, and on the projecting end of said transverse shaft 15 I mount the winding drum' 5, fixing it thereon conveniently by means of the pin 18. of the shaft 15 is provided with the usual driving-gear 19, which intermeshes with the gear 11 of the motor, but which in the present instance is made much larger than the gear 11, so as to reduce the speed with which 'the wiuding-drum 5 rotates sufficiently to adapt the engine as a whole to a proper speed of travel of a rossing apparatus attached to it up and down the standing treetrunk. The rope-6 is the fall of the tackle, whereby the rossing implements are raised and lowered along the tree-trunk. That portion of rope 6 which is, as here shown, for- Ward of the air-receiver leads to the rossing apparatus, While the stub or rear end of the roped isconveniently held bythe engine attendant and. tightened or slackened on the drum, as the operator of the rossing instruments directs. Rope 6 is readily removable from winding-drum 5. The air-receiver is provided with a nozzle having a shut-01f valve 21 and adapted for attachment of the pneumatic tube leading from the air-receiver to- The other end vIIO readiness for transportation and may be car- The combination of a base-plate; a motor havingashaft; an air-compressor having a shaft; a small gear on the motorshaft; a relatively larger gear on the air-compressor shaft and meshing withthe smaller gear on the motor-shaft; and a winding-drum 0n the shaft of the air-compressor.

In testimony whereof I affix my signature in presence of two witnesses.
